The dura foam roof system has a rigid and durable surface that you can walk on.
Roofing rigid foam.
Continuous rigid insulation is a construction solution that provides a thermally efficient building enclosure.
Polyiso is an easy cost effective sustainable and energy efficient construction material.
The purpose of the requirement that rigid foam installed above roof sheathing meet certain minimum r values is to ensure that the roof sheathing stays warm enough during the winter to avoid moisture accumulation and possible sheathing rot.
Install it anywhere from the roof to the foundation.
Rigid insulation sheathing is made of a rigid plastic foam that is typically sold in 4 8 or 4 10 foot boards.
A thick typically 1 5 thick closed cell polyurethane waterproofing barrier seals the roof against leaks.
1 inch and 2 inch thicknesses are common.
Spray polyurethane foam spf is the only roofing material that has no seams.
Install roofing underlayment flashing and cladding as per best practices.
The boards are available in several thicknesses and r values.
At r 4 it also has the lowest r value per inch.
There s a reason polyiso rigid foam insulation is used in more than 70 of commercial roof construction as well as in many residential builds.
Install nailbase for cladding.
Sprayed polyurethane foam spf is a fully adhered closed cell roofing material applied to a desired thickness usually 1 2 inches forming a seamless monolithic roof surface incorporating flashings penetrations and parapet walls.
You can even place it under the foundation slab.
Polyurethane spray foam roofing systems are frequently used to insulate and protect a wide variety of residential commercial and industrial buildings.
Rigid foam insulation also known as insulating boards provide high r values.
Spray foam is the high tech alternative to traditional roofing and insulation materials.
All three types of rigid foam insulation expanded polystyrene eps extruded polystyrene xps and polyisocyanurate are suitable for use on the exterior of walls and roofs though they do not perform equally.
Rigid insulation layers exterior to existing roof sheathing must provide sufficient thermal insulation r value to control condensation risk see climate specific guidance.
This system eliminates seams and cold joints the primary source of major roof leaks and provides a durable waterproof covering that bonds tightly to any properly.
Foam roofs are lightweight durable and seamless.
Nailbase must be vented in high snow load areas.
Eps is the most vapor permeable of the three types.
Rigid insulation is one of the best tools to reduce your energy costs.
All atlas acfoam polyiso insulation boards are qualitymark certified providing consumers an easy way to identify premium products that meet or exceed building codes for the best in roof performance.
They keep your home at a comfortable temperature without the need to crank your heat.
